Wed, 16 Nov 2016 09:55:58 +0000http://www.doxer.org/?p=5998When you issue "shutdown" or "reboot" on linux box and found "mount: you must specify the filesystem type, please stand by while rebooting the system":

Then one possible reason is that you have specified wrong mount options for nfs shares in /etc/fstab. For example, for nfsv3, please make sure to use below nfs options when you mount shares:

Service "sshd/snmpd" will accept connections from all hosts except host1.example.com. All services will accept connections from localhost. Other services will deny connections from all hosts.

Thu, 28 Apr 2016 03:32:11 +0000http://www.doxer.org/?p=5835Today when I tried to enable page-level ads of google adsense, I met below error:

This page cannot display anchor ads for the following reason(s):

The viewport is not between 320 and 420 pixels wide.

The current browser is not supported.

The cause by this is that the wordpress theme currently used didn't support viewport(more info about viewport is here). To enable viewport, we can install one plugin - Definitely allow mobile zooming. After activating them, you can try again.

Fri, 22 Apr 2016 23:41:44 +0000http://www.doxer.org/?p=5829I've been having this strange problem since this morning after starting office laptop from Hibernate. Restart is also not fixing it.

For any program, file, it just says that Windows cannot find the file ...etc . Simple search shows that it comes from anti virus. So, it is coming from Mcafee Host IPS. As soon as I turn that off from Mcaffee tray menu > Quick settings > Host IPS off, programs start working.

Tue, 19 Jan 2016 09:04:17 +0000http://www.doxer.org/?p=5756We can use iscsitarget to share local disks as iscsi LUNs for clients. Below are brief steps.

First, install some packages:

yum install kernel-devel iscsi-initiator-utils -y #'kernel-uek-devel' if you are using oracle linux with UEK
cd iscsitarget-1.4.20.2 #download the package from here
make
make install

And below are some useful tips about iscsitarget:

The iSCSI target consists of a kernel module (/lib/modules/`uname -r`/extra/iscsi/iscsi_trgt.ko)

The kernel modules will be installed in the module directory of the kernel
